Abstract:
Objective·To construct a nanoengineered T cell system and explore its synergistic efficacy in the in vitro treatment of oral squamous cell carcinoma,and provide a new strategy for this disease.Methods·Zr-MOF nanoparticles with a highly hydrophilic hyaluronic acid(HA)coating(PCN224-HA NPs)were prepared,and their carboxyl groups were activated to enable coupling with anti-CD45 antibodies through an amide reaction.High-purity CD8+T cells were then extracted from the spleens of mice,and the PCN224-HA NPs were loaded onto the T cells via the CD45 antigens on their surface.The coupling was observed using bioelectron microscopy and confocal microscopy,and free radical generation was detected under ultrasound irradiation.The viability of Cal27 cells was recorded by a microplate reader to explore therapeutic effects in vitro.Results·PCN224-HA NPs were successfully synthesized and confirmed to be coupled onto the surface of CD8+T cells,constructing a nanoengineered T cell system(T cells@PCN224-HA NPs).Free radical production was monitored after ultrasound irradiation and the viability of Cal27 cells decreased to 31.70%after in vitro treatment.Conclusions·Preliminary experiments demonstrated that the nanoparticles can be successfully loaded onto the surface of T cells,providing combined sonodynamic therapeutic effects from the nanoparticles and immunocidal effects from the T cells.This offers a novel strategy for the treatment of oral squamous cell carcinoma,with potential for further in vivo anti-tumor experiments and therapeutic applications.
